Objective This study aimed to compare and analyze the clinical efficacy and safety of late-course and simultaneous integrated dose-increasing intensity-modulated radiation therapy(IMRT) for cervical cancer complicated with pelvic lymph node metastasis. Methods Sixty patients with cervical cancer complicated with pelvic lymph node metastasis who were admitted to our hospital from January 2013 to January 2015 were enrolled. The patients were randomly divided into the late-course dose-increasing IMRT group and the simultaneous integrated dose-increasing IMRT group, with 30 cases included in each group, respectively. All patients were concurrently treated with cisplatin. After treatment, the clinical outcomes of the two groups were compared. Results The remission rate of symptoms in the simultaneous integrated dose-increasing IMRT group was significantly higher than that in the late-course dose-increasing IMRT group(P < 0.05). The follow-up results showed that the overall survival time, progression-free survival time, and distant metastasis time of patients in the simultaneous integrated dose-increasing IMRT group were significantly longer than those in the late-course dose-increasing IMRT group(P < 0.05). The recurrent rate of lymph nodes in the radiation field in the simultaneous integrated dose-increasing IMRT group was significantly lower(P < 0.05) than in the late-course dose-increasing IMRT group. There was no significant difference in the incidence of cervical and vaginal recurrence and distant metastasis between the two groups(P > 0.05). The radiation doses of Dmax in the small intestine, D1 cc(the minimum dose to the 1 cc receiving the highest dose) in the bladder, and Dmax in the rectum in the simultaneous integrated dose-increasing IMRT group were significantly lower(P < 0.05) than in the late-course dose-increasing IMRT group. There was no significant difference in intestinal D2 cc(the minimum dose to the 2 cc receiving the highest dose) between the two groups(P > 0.05). The incidence of bone marrow suppression in the simultaneous integrated dose-increasing IMRT group was significantly lower(P < 0.05) than in the late-course dose-increasing IMRT group.Conclusion The application of simultaneous integrated dose-increasing IMRT in the treatment of cervical cancer patients complicated with pelvic lymph node metastasis can significantly control tumor progression, improve the long-term survival time, and postpone distant metastasis time with high safety. 展开更多

Objective: To predict the risk factors of lymph node metastasis in cervical cancer by using large sample clinical data, and to construct and verify the nomogram for predicting lymph node metastasis. Methods: A total of 5940 patients with cervical cancer from 2004 to 2015 in the National Cancer Institute Surveillance Epidemiology and End Results database were retrospectively screened and randomly assigned to training group (n = 4172) and validation group (n = 1768). Multivariate Logistic regression analysis was used, and the optimal model was selected according to AIC or BIC and likelihood ratio test, and a nomogram was drawn. The accuracy and robustness of the prediction model were evaluated in three aspects: discrimination, calibration and clinical net benefit. Results: The prediction model based on race, tumor tissue differentiation degree, tumor histopathological type, distant metastasis of tumor, tumor diameter and other risk factors was successfully established and a nomogram was constructed. The AUCs of training group and validation group were: 0.736 and 0.714, respectively. And the p-values of the Hosmer-Lemeshow test were 0.28 and 0.11, respectively. The calibration curve was in good agreement with the ideal curve. It had high accuracy and applicability after internal verification. Conclusion: A prediction model is constructed based on the risk factors of lymph node metastasis of cervical cancer. The nomogram has a good effective prediction and can provide a theoretical basis for clinicians to assess the disease quickly before surgery. 展开更多

Objective The aim of this research was to study the prognostic significance of the number of pelvic lymph nodes removed in patients with early cervical cancer.Methods We searched the Pub Med database using the terms "cervical cancer" and "lymph nodes" or "lymphadenectomy". Studies on the association between number of lymph nodes removed and prognosis or survival were identified. We retrospectively studied the relevant research.Results Ten retrospective studies were included. Two studies indicated that the number of lymph nodes had no association with prognosis whereas three studies found a positive relationship. Five studies indicated some factors that could influence the relationship between number of lymph nodes and prognosis.Conclusion The number of lymph nodes removed may positively influence the prognosis of patients with cervical cancer. Some factors may influence the relationship between the extent of lymph nodes removed and patient prognosis. Additional multicenter, prospective studies with large samples are required to confirm the study findings. 展开更多

Spread into regional lymph node is the major route of metastasis in cervical cancer. Although lymph node status is not involved in the International Federation of Gynecology and Obstetrics staging system of uterine cervical cancer, the presence or absence of lymph node metastasis provides important information for prognosis and treatment. In this review, we have attempted to focus on the incidence and patterns of lymph node metastasis, and the issues surrounding surgical assessment of lymph nodes. In addition, the preoperative prediction of lymph node status, as well as the intraoperative assessment by sentinel nodes will be reviewed. Finally, lymph node micrometastasis also will be discussed. 展开更多

BACKGROUND Cervical lymph node metastasis in papillary thyroid carcinoma(PTC) affects the treatment and prognosis of patients. Ultrasound is a common imaging method for detecting cervical lymph nodes in PTC patients; however, it is not accurate in determining lymph node metastasis.AIM To evaluate the value of contrast-enhanced ultrasound combined with elastography in evaluating cervical lymph node metastasis in PTC.METHODS A total of 94 patients with PTC were recruited. According to pathological results,lymph nodes were divided into two groups: metastatic group(n = 50) and reactive group(n = 63). The routine ultrasound findings, contrast-enhanced ultrasound and elastography data were recorded and compared. Logistic regression was used to generate predictive probability distributions for the diagnosis of lymph node metastasis with different indicators. Receiver operating characteristic curve analysis was used to test the efficacy of contrast-enhanced ultrasound combined with elastography based on routine ultrasound in evaluating PTC cervical lymph node metastasis.RESULTS The ratio of long diameter/short diameter(L/S) ≤ 2, irregular marginal morphology, missing lymphatic portal, peripheral or mixed blood flow distribution, peak intensity(PI), non-uniform contrast distribution and elasticity score in the metastatic group were significantly higher than those in the reactive group(P < 0.05). L/S ratio, missing lymphatic portal, PI and elasticity score had a significant influence on the occurrence of PTC cervical lymph node metastasis(P< 0.05). Furthermore, the area under the curve(AUC) for lymph node metastasis diagnosed using the combination of PI ratio, elasticity score, missing lymphatic portal and LS was 0.936, which was significantly higher than the AUC for PI ratio alone. The difference was statistically significant(P < 0.05). The fitting equation for the combined diagnosis was logit(P) =-12.341 + 1.482 × L/S ratio + 3.529 ×missing lymphatic portal + 0.392 × PI + 3.288 × elasticity score.CONCLUSION Based on the gray-scale ultrasound, the combination of contrast-enhanced ultrasound and elastography can accurately assess PTC cervical lymph node metastasis. 展开更多

The aim of the present study was to examine the relationship between the protein expression of vascular endothelial growth factor(VEGF) and lymph node metastasis(LNM) in papillary thyroid cancer(PTC). VEGF-related articles that had been published until August 2016 were searched from the Pub Med, EMBASE, and MEDLINE to identify the risk factors of LNM in PTC. Rev Man 5.3 software was used for the meta-analysis. Finally, 9 articles met the inclusion criteria and were included in our meta-analysis. LNM was found to be present in 176 of 318 patients(57.8%) with high VEGF expression and in 71 of 159 patients(47.0%) with low VEGF expression. The overall OR was 2.81(95% confidence interval, 1.49–5.29). LNM occurred more frequently in patients with high VEGF expression than in those with low VEGF expression(P=0.001). Heterogeneity was markedly decreased in the subgroup analyses of LNM in terms of the patients' country of origin and the detection methods. Our meta-analysis concluded that the VEGF protein expression is associated with LNM in PTC. 展开更多

Objective: To assess the value of sentinel lymph node (SLN) localization by lymphoscintigraphy and gamma probe detection in early cervical cancer. Methods: A total of 27 patients with operable invasive early cervical cancer and clinically proved negative pelvic lymph nodes were included in this study. The 99Tcm-dextran of 74 MBq (2 mCi) was injected around the cervix at 2 and 10. Lymphoscintigraphy and gamma probe detection were used to find the SLN. Results: The SLN was identified in 27 patients. The sensitivity and specificity of the SLN detection to predict the metastasis of the pelvic lymph node were 100% and 100% respectively. Conclusion: Identification of the SLN using radionuclide is feasible and possible in women with early cervical cancer. 展开更多

The current status and future prospects for diagnosis and treatment of lateral pelvic lymph node(LPLN)metastasis of rectal cancer are described in this review.Magnetic resonance imaging(MRI)is recommended for the diagnosis of LPLN metastasis.A LPLN-positive status on MRI is a strong risk factor for metastasis,and evaluation by MRI is important for deciding treatment strategy.LPLN dissection(LPLD)has an advantage of reducing recurrence in the lateral pelvis but also has a disadvantage of complications;therefore,LPLD may not be appropriate for cases that are less likely to have LPLN metastasis.Radiation therapy(RT)and chemoradiation therapy(CRT)have limited effects in cases with suspected LPLN metastasis,but a combination of preoperative CRT and LPLD may improve the treatment outcome.Thus,RT and CRT plus selective LPLD may be a rational strategy to omit unnecessary LPLD and produce a favorable treatment outcome. 展开更多

Background In general,sentinel lymph node (SLN) can reflect the whole state of the entire drainage area. The present study evaluated the clinical significance of sentinel lymph node identification in the treatment of early stage cervical cancer.Methods Twenty-eight patients with early stage (Ia-IIa) cervical cancer undergoing radical hysterectomy and pelvic lymphadenectomy were included in this study. At two locations 8 hours before operation,0.4 ml 37 Mbq technicium-99 labeled dextran was injected intracervically. After that,preoperative lymphoscintigraphy was performed to detect SLNs. During the operation,lymph nodes were detected ex vivo by a γ-counter to identify SLNs. The samples of SLNs and non-SLNs were used for pathological examination separately and compared with the final results. Results SLNs were identified in 27 of 28 (96.4%) patients. A total of 123 SLNs were identified from 814 nodes. Six patients had altogether 11 positive lymph nodes,which were all SLNs. No patient had false-negative sentinel node. Conclusion SLNs can successfully predict the lymphatic metastasis in patients with cervical cancer. The clinical validity of this technique should be evaluated prospectively. 展开更多

Background:Pelvic lymph node metastasis (LNM) is an important prognostic factor in cervical cancer.Cervical squamous cell carcinoma accounts for approximately 75-80% of all cervical cancers.Analyses of the effects of the number of positive lymph nodes (LNs),unilateral vcrsus bilateral pelvic LNM and a single group versus multiple groups of pelvic LNM on survival and recurrence of cervical squamous cell carcinoma are still lacking.The study aimed to analyze the effects of the number of positive pelvic LNs and a single group versus multiple groups of pelvic LNM on survival and recurrence.Methods:We performed a retrospective review of 296 patients diagnosed with Stage ⅠA-ⅡB cervical squamous cell carcinoma who received extensive/sub-extensive hysterectomy with pelvic lymphadenectomy/pelvic LN sampling at Peking University People's Hospital from November 2004 to July 2013.Ten clinicopathological variables were evaluated as risk factors for pelvic LNM:Age at diagnosis,gravidity,clinical stage,histological grade,tumor diameter,lymph-vascular space involvement (LVSI),depth of cervical stromal invasion,uterine invasion,parametrial invasion,and neoadjuvant chemotherapy.Results:The incidence of pelvic LNM was 20.27% (60/296 cases).Pelvic LNM (P =0.00) was significantly correlated with recurrence.Pelvic LNM (P =0.00),the number of positive pelvic LNs (P =0.04) and a single group versus multiple groups of pelvic LNM (P =0.03)had a significant influence on survival.Multivariate analysis revealed that LVSI (P =0.00),depth of cervical stromal invasion (P =0.00)and parametrial invasion (P =0.03) were independently associated with pelvic LNM.Conclusions:Patients with pelvic LNM had a higher recurrence rate and poor survival outcomes.Furthermore,more than 2 positive pelvic LNs and multiple groups of pelvic LNM appeared to identify patients with worse survival outcomes in node-positive ⅠA-ⅡB cervical squamous cell carcinoma.LVSI,parametrial invasion,and depth of cervical stromal invasion were identified as independent clinicopathological risk factors for pelvic LNM. 展开更多
